Specification forming part of Letters Patent No. 191,282, dated May29,1877 application filed April 9, 1877.

To all whom it may concern:

Be it known that I, GEORGE HERSMAN, of Hersrnan, in the county of Brownand State of Illinois, have invented certain new and useful Improvementsin Hay-Elevator; and

.I do hereby declare the following to be a full,

clear, and exact description of the invention, such as will enableothers skilled in the art to which it pertains to make and use it,reference being had to the accompanying drawings, which form part ofthis specification.

The nature of my invention consists in the construction and arrangementof a hay elevator and loader, as will be hereinafter more fully setforth.

The annexed drawings, to which reference is made, fully illustrate myinvention.

A represents a barn, hay-mow, or other similar building. Along theridge, within the house A, is a beam, B, on each side of which, alongthe lower edge, is formed a track, a, as shown. B represents anextension beam, provided with tracks a on its sides, and on top it hassuitable truss-work B to strengthen the beam. The outer end of theextensionbeam B is supported on each side by means of braces C and O, inthe manner shown in the drawing. These braces are so arranged that theyhold the ends of the beams B B together, they being further united bydowel-pins. A third beam, D, is placed against the outer end of theextension-beam B and supported by braces D against the braces O G. Fromthe beam D are suspended two pulleys, E E These various beams and bracescan be easily and quickly put up and taken down again, as required. Grepresents the car or carriage suspended under the beams B B by means ofwheels d d running upon the tracks a a. On each side of the car G is apivoted hook, H, pressed downward by means of a spring, 11, so as tocatch on a lug, e, on the side of the beam B to hold the car firmlywhile the load is being hoisted. The rear ends of the two hooks H H areconnected by means of a crossbar, I, at the end of the car, and thecenter of said cross-bar is bent to form a loop or bend, f,projectingfidownward, as shown. At the front end of the car G isattached a rope, h, which passes over the inner pulley E, under the beamD, then around a pulley, E, from which a weight, K, is suspended, andfrom this pulley the rope passes over the outer pulley E around theouter end of the beam D, and is attached to the end of the truss-work BJ is the hoisting-rope, which passes out through an aperture at theopposite end of the house A. This rope lies in the loop or bend f of thecross-bar I, and passes over a pulley, K, within the car. This end ofthe rope I is, by a short chain, m, connected with the fork, or otherdevice, for holding the load. This chain and hoisting-rope are guided tothe pulley K by means of an annular weighted guide, L, through which therope passes, said guide being suspended by cords n n from a bail, M,pivoted to the sides of the car.

The car being held over the load of hay by hooks H H catching upon thelugs ee, the fork or other hoisting device is loaded in the usualmanner. The hoisting-rope J is then operated to raise the fork, the carremaining stationary until the chain reaches the loop or bend f. Thischain being too large to pass through said loop, the cross-bar I is, bythe strain on the hoisting-rope, depressed so as to raise the hooks Hfrom the lugs 0, thus disengaging the carriage, and the carriage willthen pass along the tracks a, a into the mow to any point where it isdesired to deposit the load. As the'car thus moves inward it takes therope h with it, the weighted pulley E rolling on said rope, between thepulleys E E As soon as the load has been deposited, and the strain onthe hoisting-rope released, the weighted pulley E at once carries thecar back to its former position, where it is retained by the hooks Hcatching on the lugs e again.

This device may be applied to many other purposes, as well as forloading and stacking hay and straw.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-- 1. The combination, with thestationary ridge-beam B, having tracks a a, of the detachable beam Bwith tracks a a, detachable braces O C, and the detachable beam D, withbraces D and pulleys E E substantially as and for the purposes hereinset forth.

2. The combination of the car G with its wheeled d, the pivoted hooks HH, springs d,

cross-bar I, with loop or bend f, and the lugs In testimony that Iclaim, the foregoing I ee,substantiallyas and for the=purposeshereinhave hereunto set; my hand this 24th day of set forth. March, 1877'.

3. The combination, with the car G, of the hoisting-rope J, chain m,cross-bar I, connect- GEORGE HERSMAN. ing the hooks H, the pulley K, andthe annular weighted guide L, suspended from the piv- Witnesses-z otedbail M, all substantially as and for the JOHN J. MGDONNOLD, purposesherein set forth, NELSON LOVEITT.
